Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed February 27. 1907- Serial No. 359|626.

To all whom it may concern:

Be it known that I, KARL KsZEGI, subject of the Emperor ofAustria-Hungary, residing at Baja, in the Empire of Austria- Hungary,have invented new and useful Improvements in Motor-Driven Cultivating-Machines, of which the following is a specification.`

This invention relates to a motor-driven self-propelled cultivating andsowing machine, wherein a plow, harrow, ridge-drill and a roller arecombined, and has for its object to completely cultivate the soil i. e.to loosen the soil and finally roll the sown seed in one singleoperation without the employment of beasts of draft. For the purpose ofeconomizing power and more thoroughly cultivating the soil, the ordinaryplowshares are replaced by a novel contrivance for hoeing up the ground,wherein crank operated hoes successively hoe the ground to anyadjustable depth and completely turn up the same during the working ofthe machine but during the return of the engine, the cam controlled hoesare idle i. c. do not penetrate into the soil. This hoeing contrivancecan be rendered operative or inoperative independently of the harrowing,sowing and rolling devices by means of suitable ratchet 4gear and viceversa the harrowing, sowing and rolling devices may also be renderedoperative or inoperative simultaneously and independently of the hoeingcontrivance and moreover all devices can be rendered operativesimultaneously when the machine is to be started or they can be renderedinoperative when the motor only serves for propelling the machine ineither direction.

The accompanying drawings represent by way of example one constructionalform of this machine. Figure 1 is a longitudinal vertical sectionthrough the machine; Fig. 2 is a section on line in Fig. 1; Fig. 3 is asection on line g/-g/ in Fig. 1; Fig. 4 is a side elevation of thehoeing contrivance on an enlarged scale Fig. 5 shows the operation ofone single hoe; Fig. 6 shows the rear view of a hoe and the verticalcross-section of the cam controlling the hoe and Fig. 7 is a section online z-z in Fig. 6.

As shown in the accompanying drawing7 the machine consists of a frameprovided with a roof, the motor and all other devices being suitablyarranged on the said frame. This movable frame constitutes an elongatedhorizontal ironl frame 1 bearing on two pairs of wheels 2, 2 and 3, 3respectively and supporting the roof 5 by means of the pillars 4. Thefront pair of smaller wheels 2, 2 can be turned to the right or left forthe purpose of steering the machine by means of the hand wheel 6 andtoothed gear 7, 8 and the chain gear 9, 10, while the rearward pair oflarger wheels 3, 3 are rotatably mounted on an aXle 12 fixed in bearings11 (Fig. 2) on the frame 1. The front part of the frame 1 is in the formof a platform 13 and the rear part in form of a platform 14.

The motor 15 arranged on the platform 13 and the caster or rudder wheel6 are operated from the platform 13 and the h oelng, harrowing, sowingand rolling contrivances as well as the ratchet and adjusting mechanismsare operated from the platform 14. Both platforms are accessible bymeans of steps 16. vThree horizontal shafts 17, 18 and 19 for drivingthe machine are mounted in side standards or uprights attached to theframe 1 between the motor 15 and the pair of wheels 3, 3. The shaft 17is operated from the motor 15 by the bevel gear 20 and causes the shaft18 to move slower by means of the spur wheels 21 and 22. The shaft 18carries a spur Wheel 26 capable of a sliding movement from the platform14 by means of the handwheel 23, adjusting shaft 24 and adjusting fork25. The spur Wheel 26 in one end position engages ina spur wheel 27 onthe shaft 19 and rotates the shaft 19 in the direction indicated by anarrow and in the other end position, the spur wheel 26 engages in areversing gear 29, 30 and drives the shaft 19 in the opposite direction,the said reversing gear being in permanent engagement with the toothedwheel 27 and loosely mounted on the stud 28 near the shaft 19. The spurwheel 26 does not engage with any part in the middle position .and theshaft 18 then runs idle and the shaft 19 is stationary. N ow the shaft19 is connected by sprocket wheel gear 31, 32, 33 to the hollow shaft`34of the wheels 3 which is loosely mounted on the stationary axis 12 andconsequently, this pair of wheels 3 can be moved forwards or backwardsfrom the shaft 19. The whole car may also be moved forwards or backwardswhen the Wheel 26 of the shaft 18 is brought into either end position.

The sprocket wheel 33 of the vsprocket wheel gear 31, 32, 33 is notrigidly connected with the hollow shaft 34 but coupled therewith (Fig.2) after the manner of the differential gear known especially inconnection with automobiles as the shaft 34 is divided and formed at thesplit ends into face wheels 35, wherein conical coupled toothed wheelsengage, which are mounted in the usual manner in the sprocket wheel 33loosely arranged between the face wheels 35. This construction has forits object to enable the wheels 3', 3 .to make an independent relativerotation with respect to the turns of the machine and this constructionmay of course be replaced by any other construction answering the samepurpose, trivance is arranged within the frame 1 between the pair ofwheels 3, 3 and the rearward platform 14. This hoeing contrivanceconsists of a frame formed by two lateral vertical frames 36 and thetransverse bars or rods 37 uniting the latter. The said frame' isrotatably mounted at the front on the stationary axis 12 and through theinstrumentality of a screw 38 and handwheel 39 the frame is adapted tomove up and down rearwardly on a horizontal crossbeam 40 rigidlyconnected to the frame 1. For the aforesaid purpose, this screw 38 islinked with its lower end to the rearmost transverse bar 37 and mountedwith its free end in the hand wheel 39, which is secured in thecross-beam 40 against axial displacement but can be easily rotated.

There is arranged in the rearward part of the said frame a horizontalshaft 41 which carries six cam disks 42 each beingadjusted at an angleof 60. Each disk 42 carries an eccentric ring 43 which is formeddownwards into an arm 45 (Figs. 4, 5, 6) bearing a hoe 44 and upwardsinto an ear 46. A crank shaft 47 having six cranks adapted to turn at anangle of 60o is mounted in the frame between axis 12 and shaft 41. Noweach crank 48 is coupled by a connecting rod 49 to an ear 46 of theeccentric rings 43. The crank shaft 47 carries a sprocket wheel 50 whichis driven in the direction of the arrow (Figs. 1 and 2) by the chain 51and the sprocket wheel 52 loosely mounted on the hollow shaft 34 of thevwheels 3. The sprocket wheel 52 is rigidly connected by its hub 53 to asecond sprocket wheel 54, which is driven by the chain 55 and thesprocket wheel 56 loosely mounted on the shaft '17, when this sprocketwheel 56 is coupled to the shaft 17 by means of the friction coupling 57(Fig. 2). The coupling 57 as well as the toothed wheel 26 on the shaft18 are operated by the adjusting fork 60 adapted to be actuated from theplatform 14 by means of the handwheel 58 and the adjusting shaft 59. Thecrank shaft 47 adapted to be driven by the shaft 17 in the manner hereindescribed is kso connected to the cam shaft 41 by a The hoeingconsprocket wheel gear 61, 62, 63 or in any other speed and in the samedirection when the shaft 47 is driven. The hoes 44 derive from therotating crank shaft 47 a pendulum oscillation vertical to the shaft 41and imitatin under the influence of the cams the manna labor when hoeingup the ground, because the cam disks 42 are so adjusted that the hoeswhen oscillating rearwards in the direction of the arrow T (Fig. A5) "Le. the working period during which they penetrate with their point intothe ground and turn and hoe up the same, are guided'by the cams in `alower path when oscillating forwards (direction of arrow Il) but duringthe unefective motion in a higher path in such a manner that'the hoes donot come in contact with the earth. This is clearly obvious in Fig. 5wherein six stages of the stroke of a hoe are shown and the curve 64represents the path described by the point of the hoe, which path ingdepths by altering the eccentricity ofthe corresponding adjustable cams.The line a-c represents the soil and the shaded part cut away from thecurve 64 through the said line represents the earth cultivated by thehoe. The upper part of the curve 64 represents the idle motion and thelower part the working motion of the hoe.

It is obvious that the hoes 44 only hoe and turn up the soil when theentire hoeing contrivance is correspondingly lowered by means of thedescribed handwheel .39 te. turned downwards on the axis 12;. A platesuspended to the foremost transverse bar 37 of the hoeing contrivancebetween the crank shaft 47 and the shaft 34 protects the latter and thewheels etc. thereon from the earth thrown up by the hoes.

The harrow which is adapted to be raised and lowered is located underthe platform 14 behind the above-described-hoeing contri-vance. Thisharrow is a rake having downwardly directed vertical prongs 65, whichhorizontal ends in a plate 66 which is capable of a horizontal slidingmovement in a frame 67 in both directions and can also be lcaused tomake a lateral oscillatory movement from the shaft 17 in the said frame67. For this purpose, there is provided at the side of the frame 1 ofthe machine a horizontal shaft 68 (Figs. 2 and 3)-which carries at therearward end a downwardlyv directed arm 69 and at the front end anupwardly directed arm 70,.

the periphera groove 72 of a cam disk 7.3 keyed on to the shaft 17, saiddisk causing the shaft 68 to oscillate. The other arm 69 is coupled by aconnecting rod 74 to a pivot 75 on the plate 66, so that the shaft 68 aswell as the plate 66 are moved to and fro. l The frame 67 guiding thesaid plate 66 is may ofcourse be varied for any desired work-I aresecured with their upper forwardly bent suitable mannerthat both movewith equal The latter engages with a guide roller.71 in adapted to moveup and down in lateral vertical guides 77 against a vertical transversewall rearwardly shutting off the car frame under the platform 14 and issupported by a screw 78 which is mounted in a standard 79 arranged onthe platform 14 and can be raised or lowered by means of the handwheel80 in the form of a nut so that the frame 67 may be raised or loweredaccordingly. 1f this frame 67 is lowered to such an extent that thepoints of the harrow prongs 65 touch the soil, the laterally oscillatingprongs 65 which are also moved forward by the motion of the car harrowthe earth which has been hoed up by the hoes 44 in a uniform rapidmanner and thus make this earth ready for the reception of the seed.

There is,arranged at the outermost end of the platform 14 the seedreceptacle of any known ridge drill, from which the seed guide tubes 82lead to the known sowing blades 83, the levers 84 of which are connectedto a shaft 85 mounted above on the frame 67 There is also attached tothe same shaft 85 the known roller 86 by means of lateral arms 87 andthese arms as well as the levers 84 are supported by a horizontal bar 88which is carried by thearms 89 connected to the shaft 85 and frame 67(Figs. 1 and 2) so that when the latter is raised, not only the harrow65 but also the plowshare levers 84 of the sowing machine and the roller86 are raised and consequently rendered inoperative. lf however theframe 67 is lowered to such an extent that the roller 86 rests on theground, the plowshare levers 84 and the harrow 85 also penetrate intoand cultivate the soil.

The manipulation and operation of the machine can now be readilyunderstood from the preceding description. The machine may first of allbe transported to the working spot by means of its own motor 15, forwhich purpose, the latter is only started when the boeing, harrowing,sowing and rolling devices are raised and the toothed wheel 26 is in themiddle position, whereupon'when this wheel 26 is placed in either endposition by means of the handwheel 23, the entire machine will moveforwards or backwards by means of the chain gear 31, 32 and 33.

l/Vh en the machine has arrived at the working place, it is brought intothe proper working position i. e. with the platform 13 at the front andthe wheel 26 is turned into the middle position, so that the machine isstationary but the motor is running. Now the hoeing contrivance is setin motion by means of the friction coupling 57 actuated by the handwheel58 and is slowly lowered by means of the handwheel 39 and the screw 38until the hoes 44 hoe and turn the earth to the necessary depth. Whenthe hoeing contrivance is adjusted, the harrow, the sowing machineplowshare levers and the roller are lowered in the described manner bymeans of the handwheel 80 and the wheel 26 is coupled with the toothedwheel 27, whereupon the whole machine moves forward and hoes Aand turnsup the earth, harrows the hoed and turned up earth, places the seed inthe harrowed earth and simultaneously covers the seed by rolling.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, 1 declare thatwhat I claim and wish to secure by Letters Patent is z` 1 A motor drivencultivating machine, comprising a shaft 41, hoes eccentrically mountedon said shaft at an angle, and means for successively oscillating saidhoes, substantially as described.

2. A motor driven cultivating machine comprising a shaft 41, angularlydisposed eccentrics mounted on said shaft, rings 43 mounted on saideccentrics, a hoe connected to each ring, a crank shaft 47, pitman rodsconnecting the cranks of said shaft with the rings 43 whereby said hoeswill be successively operated on the rotation of the crank shaft,substantially as described.

3. A motor driven cultivating machine, comprising a main axle, a framehaving one end swiveled thereon, means for engaging the other end ofsaid frame for adjusting it vertically, a crank shaft 47 in said frame,means for driving the same, a shaft 41 also mounted in said frame,angularly disposed eccentrics 42 on said shaft41, aring 43 mounted oneach eccentric, a hoe carried by each ring, and a pitman rod connectingeach ring to a shaft on the crank shaft, whereby the hoes will besuccessively oscillated, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of i two subscribing witnesses.
